Lane Kayn Guide - What i have learned in 20 games (i'm not a pro)

I have been playing Kayn non stop since release and this is what i learned so far (this guide is for TOP and MID lanes) Also, i am not a pro, this are just thoughts of a regular person.

1-Assassin Kayn is useless without at least ONE defensive item and it better be your FIRST item or (i like frozen mallet better because it gives DOUBLE the health and only have less 10 AD than Black Cleaver)

2-If you want to play Bruiser Kayn i recommend your first item to be . Because Kayn loses all matchups in the Top lane if you decide to START with pure offensive items.

3-The job of bruiser Kayn is to be a meat shield, use your stun, and slow oponents with . This is as much utility as Kayn can have. Here is a possible build for "bruiser annoying Kayn" (items in order for TOP LANE AGAINST ANOTHER AD CHAMPION)
You might be thinking "what about defense against AP? Well your raw HEALTH is defense against AP. and give you 1125 raw health! Thats more than enough defense against AP (if the enemy team has more than 1 AP user do early) Also give you enough AD for your "red form" to do decent damage and steal enough HP with your ULTY (i think its about 20%).

4-Assassin form is a little bit weak at the moment but if you want to play it go full Lethality with and Just an example of how a Assassin build should look like I really don't like on assassin Kayn because you are already going full Lethality and you are not going to focus Tanks anytime soon. Also, did i mention Frozen Mallet gives DOUBLE the Health? Your job is to focus the mid laner, ADC and other assassins.
